Without a distribution network, theres no way this Jet A will be used to fuel (many) Delta airplanes.

Delta will still have to use middle men. Buying from different sources across the country/world. So, in essence, this has nothing to do with their airplanes and they're just getting involved in the oil refining business. Doesn't make much sense to me... Delta is an airline, they know about flying airplanes.

Why not just invest in an oil refining company instead of buying an actual refinery and trying to act like you know what you're doing in a completely different industry?
